I wish more than anything that I had pursued a couple of languages and could speak/read fluently in them. I sort of fell in love with German in high school and took a year of it there and another two (?) years in college. At that point one has to be a complete idiot not to continue and complete the process. Well, say hello to the idiot. I could pick it up again even now, but...
Dabbled in Spanish, taking the mandatory class or two in Florida (I’m trying to remember which year(s) that was), and a year of Italian in college. But my tongue simply doesn’t take to those so well, nor did I have the necessary level of interest.
The new one I’d choose right now would be French.
